International Comfort Products H8MPV050B12B1 Air Pressure Switch
The main job of the switch is to determine whether or not the main blower is running properly. This switch is part of a small, but important collection of facets of the HVAC safety checks that are dedicated to keep you safe. A lot of switches can have a manual reset, which forces the system to be reset physically before you can continue using the system.
Symptoms to Look for when the Switch is Starting to Go Bad
- The correct temp seldom reached.
- The furnace refuses operate.
- Wrong voltage range being read from the pressure switch.
